Thermostatic fan on P0 acting up
I'm running firmware 1.18.2 and things were going well for the first 30 print hours then my thermostatic fan connected to P0 started acting up. Now I can't get it to work at all but if I swap it to an always on connector it runs fine. I don't think the FET is bad because I can switch it on/off and set speed via G-code M106.
I was using
M106 P0 S0 I0 F500 H1 T40
Could it be the PWM frequency or something in 1.18.2?
Try changing S0 to S1 in that command.
Thanks that did the trick.
